Whether it's your own child, a god child or your niece or nephew - take a day and accompany a little one on their school field trip. Take this time to bond with the child and learn. Children are great teachers and in most cases do not realize it. For the most part, children are very free-spirited and see the world with an open lense therefore they can offer any Christian a refreshed outlook on life. A child's word is pure and innocent, they will offer you an honest opinion and outlook on life and its surroundings.
So no matter where the field trip is, you'll enjoy a fantastic spiritual journey.
